Patent NO-166382-C (NO)
Inventor: JAHN HELMUT
IPC: G01N15/00
Filed: 1986-06-20
Abstract: The deformability measurement chamber is subdivided by a foil into two chamber spaces. The foil has a passage opening, the diameter of which is smaller than the diameter, at rest, of a red blood corpuscle. A static pressure gradient exists between the two chamber spaces, so that a flow takes place from one chamber space to the other. In the region of the passage opening there is situated on each side of the foil an electrode, which is connected to an alternating voltage source. In order to achieve a measurement signal which is approximately one order of magnitude greater, at a given alternating voltage frequency, a current-measuring operational amplifier is disposed in the connecton of one electrode to the voltage source.

IPC: D21H27/10
Filed: 1992-10-27
Abstract: The present invention relates to a packaging material for reduced transfer from a package to its content of substances causing undesirable taste and/or hazardous substances, this reduction being due to the packaging material containing a hydrophobic zeolite. More specifically, the invention concerns paperboard, in which case the substances causing undesirable taste mainly are naturally occurring extractive substances, oxidation products thereof and, to a lesser extent, the paper chemicals present. Further, the presence of a hydrophobic zeolite in the paperboard enhances the water-repellent (hydrophobic) capacity. Also, the present invention concerns a method for production of a packaging material of paper, board or paperboard by forming and dewatering a suspension of lignocellulose-containing fibres, where the dewatering takes place in the presence of a hydrophobic zeolite. Moreover, the present invention relates to the use of a hydrophobic zeolite for production of a packaging material, as well as the use of the thus-produced packaging material in packages for solid or liquid foodstuff, tobacco or medicines.

Abstract: A magnetic resonance signal of a volume of interest within an object is acquired by placing the object in a magnetic field and the  application  of  three  successive  steps.   The  first  step comprises an rf selective 90° pulse of frequency f x applied in the presence of an x-gradient magnetic field to select a slice. The magnetisation of the slice is then inverted.   In the second step an rf selective 90° pulse of frequency f y is applied in the presence of a y-gradient magnetic field to excite a strip of the slice.  In the third step an rf selective 180° pulse of frequency f z is applied in the presence of a y-gradient magnetic field to refocus  the  magnetisation  of  a  region  of  said  strip.   The resulting  free  induction  signal  is  derived  solely  from  said region.

Abstract: A method and apparatus for forming expandable and collapsible shielding material wherein adhesive is applied to one side of a flat tubular strip 10 which is wound around support rolls 24,26, the adhesive bonds together successive layers of strip to form a continuous loop 22 of stacked strip.  During the winding of the strip, the strip is maintained in a flat, straight condition for a time sufficient to allow the adhesive to achieve an initial set, thereby preventing the final product from having a curved set.  After the desired number of layers are wound into the loop, the loop is removed and cut through at one point to form a single, straight stacked section of definite length which is expandable and collapsible to form a shielding or insulating material having parallel hollow cells running perpendicular to the direction of expansion and collapse.
